Motion Trails v01

This is the first experiment in a webcam study I am doing using Processing. Movement results in circles of colour taken from the webcam footage. More movement results in fewer, larger circles and vice versa.

In order to use this code you need to install WinVDIG 1.01. This can be obtained from Dan Shiffman’s site. I would recommend a good quality webcam in a well lit room (I’m using the Logitech Quickcam Pro 5000). Also a powerful machine is required for the best results.

The FrameDifferencing code by Golan Levin was used as a basis for this sketch. This can be found in the Processing examples.

    I’m not sure you need it if you’re on a mac

    This is awesome too, do you think it would be possible to apply this to a quicktime movie that you have already made, instead of a live web cam? Im new to processing but love everything im seeing. I just want to dig in!!!

    Thanks Jamison.

    Yes you can create effects such as these to a quicktime movie. It’s just a case of comparing the current and previous pages. I haven’t worked with pre-recorded footage myself but have seen it done in Processing with great results – see http://www.whiteglovetracking.com/gallery.html for some great examples.

    Awesome! You inspired me to make this video. I just made a few small changes to your code: http://www.vimeo.com/2382875

    Always good to see people enjoying and experimenting with the code. Looks like you’re quite a mover too :P

    Thank you so much for this Processing code. I’ve spent several sleepless nights this week tweaking it’s parameters, to see where it might go…I feel like a whole artistic career could be springboarded off this work of yours.

    I’ve already used it to help contextualize “gesture drawing” in an Intro to Visual Art class.

    here are some links to a couple videos and sketches I’ve gotten thus far.

    Sorry if this is so derivative at the moment…I’m hoping to push it somewhere new…and in the meantime turn on my students, and anyone else I can to your work.

    Thanks Justin. It’s always great to see the results of people playing with my code. I look forward to seeing where else you take it.

    Hi James, I wish to congratulate you for your excellent work. I used your code in my studies and developed a little game where control is performed by colored objects. This is the link for the job I did. Thanks for sharing your studies to help other people.
